Abstract
En 中文
The paper presents the concept of an autonomous underwater glider with passively adapting flapping wings. The advanced system features consisting of a flapping foil glide concept, a partially pressure-neutral system approach and an automated mission preparation are explained and discussed. Furthermore, a conceptual design for a system with a length of 2 meters, a wingspan of 1.2 meters and a weight of 60 kg is presented. Compared to existing systems, the glider is characterized by an improved suitability for tilt-sensitive sensor technology, increased user-friendliness and improved modularity. The system is intended to be an extension for global ocean monitoring networks as well as a cost-effective research vehicle even for small scientific institutions. Despite the partly pressure-neutral approach, the battery capacity is comparable to that of conventional gliders following a pressure-resistant design. In order to provide the user with an adaptable and flexible system, an open source approach is adopted. Apart from the advantages there are also some challenges that need to be addressed. Special attention must be paid to the hydrodynamic design of the flow cover, the component arrangement and the systems compressibility.
